Floating fingers are generally referred to as floating bunions, and the purpose of the surgery is so that the child’s thumb function can be improved in some way. The risks of floating bunion surgery are the same as the risks of surgery in general. The risks of surgery are routine, but there is some variability in the results and impact of the surgery due to the different surgical options. Nowadays, we treat bunions from the perspective of preserving the five fingers, and there are two main options, metatarsal bone reconstruction and hallux valgus bone graft reconstruction. Metatarsal reconstruction is a reconstruction of the first metacarpal bone from the foot, which has a certain risk of bone resorption and necrosis. Because the foot is an important weight-bearing area, it will be more or less affected after the surgery. The child should not be too young for the surgery and should not be able to go down to the ground for at least three months after the surgery, but only be able to sit or lie down, and many parents will be very concerned about this because they think that their child’s hand is already not very good, and if the foot is affected as well, then the surgery would be too costly. Semi-metacarpal Bone Graft Reconstruction takes bone from the hand to rebuild the first metacarpal bone, which has a much smaller chance of bone resorption and necrosis, and will not cause additional trauma to other parts of the body, so the child can just pay attention to his/her hands after the surgery. Semi-metacarpal bone grafting can be done when the child is around 6 months to 1 year old, so that the child can establish the function of the thumb as early as possible, which is more favorable to his/her physical and mental development.
